RUFFLING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 296,740, dated Aprill5, 1884.

I Application filed August 11, 1883. (Modcl.)

Beit known that I, HARRY C. GooDRrcI-r, residing at Chicago, in thecounty of Cook and State of Illinois, and a. citizen of the UnitedStates, have invented a new and useful Iniprovement in ItuftlingAttachments for Sewing-Machines, of which the following is a fulldescription, reference being had to the accompanying dra-wings, inWhichp Figure l is a side elevation; Fig. 2, a bottorn view; Fig. 3, abottom view' of the frame, partly broken away; Fig. et, an endelevation; Fig. 5, a side elevation of the frame with the other devicesremoved, showing the opposite side to that shown in Fig. l; Figs. 6 and7, a side and edge view, respectively, of the gage, Figs. S and 9, abottom and an edge view, respectively, of the separator.

The objects of this invention are to simplify the construction andimprove the operation of rniiing attachments for sewing-machines byemploying in the construction of such devices a supporting frame orstandard, a swinging arm carrying the ruling-blade, and an actuating-armby which, through the reciprocating movement of the needle-bar, the armcarrying the rufiing-blade is oscillated, the actuating-arm and the armcarrying the ruflingblade having a common pivotal point, therebyreducing the amount of friction and rendering the device easier inoperation, with less Wea-r on the parts; and its nature consists inproviding an actuating-arm having at its acting end, on opposite sides,lips or projections to engage with set-screws or other bearing-pointscarried by the arm which supports the rufing-blade to oscillate sucharm,and combined with a supporting frame or standard, all as hereinaftermore specifically described, and pointed out in the claim. v

In the drawings, A represents the actuatingarm, hr ving at one end aslot, A', by means of which a. connectionis made with the needlebar of aserving-machine by' engagement with the set-screw for the needle, orotherwise, and having at its opposite end lips or projections e of,located on opposite sides of the body of the arm, as shown in Fig. l,one of which, a, has an inclined engaging-face, and the other a curvedengaging-face, which faces, however, may be otherwise formed.

which is an opening of suitable dimensions.

and shape to receive the end of the presserbar of the sewing-machine, towhich the head or socket C is securely clamped by a thumb or set screw,c. The body of the fra-ine or support C is provided at the proper pointwith an opening, c, for the passage of the needle.

'The under face of the body or main portion of the frame C has aportion, c, in the edge of which .are formed slots e', through which theedges of a folded ribbon or strip of cloth or other material are passed,to be stitched to the piece acted on, for the purpose of forming a Weltat a seam.

D is a rufding-blade, made of a piece of sheetsteel or other suitablematerial, and having at its acting end teeth d to engage the material,and a slot or opening, d', for the passage of a needle, as usual, andattached by riveting or otherwise to a side extension, B, on the lowerend of the arm B, vas shown in Fig. 2, so that the oscillations of thearm will move the blade forward and back, and the distance traveledbythe blade in its forward and bach movements is regulated by theset-screws b b,Which can be madey to project to a greater or lessextent, as required, for the desired throur of the blade. E is a gagelocated on the pivot for the arms A B, and between such arms, and havingon its lower or free end gage-marks f, by means of which the desiredWidth of ruffle can be determined, a pointer, j", being attached to thearm B belenT the edge of E, in

line with Which the marks on E for the desired width of tuch arebrought, setting the arm B to give the blade D the required amount ofthrow. This gage E on one edge has an outwardly-turned lip orprojection, g, to engage the end of the screw b and set the gage E atthe mark required for the Width of ruf- IOO de, and beA engaged by theprojection a andv move the arm B back, the forward movement being madeby engagement of the projection c with the end of the screw b. Vhen thegage is not used, the projection a engages directly with the end of thescrew b to carry the blade back, and when it is not desired to be Veryprecise as to the width of ruffle the gage E can be dispensed with andthe device operated in a successful manner.

F is a guide slipped onto the extension Bl of the arm B, to guide andhold the material operated on in its passage beneath the rui ning-blade.

G is a separator formed of a piece of sheet metal, having an opening, i,for the passage of a set-screw, by which it is attached to the bed-plateof a sewing-machine, and having its acting end G provided with a slot,j, which, when the separator is in place, comes in line with the slot din the blade D for the passage of the needle, the opposite end of theacting portion having a lip, k, which is struck up so as to leave anopening between its under face and the face of the end G for the passageof the material acted on, the lip or tongue k forming the means forkeeping the material down to place. The form of this separator is shownin Figs. 8 and 9, and, as shown, the separator on its main or bodyportion is provided with an edge or ledge, Z, to form a guide for theedge of the material and keep it in a straight line of travel 4when theseparator is used in connection with the rufiling devices.

The arm A is pivotally connected with the standard or frame C by a pinor screw, IL, the

stem of which passes through an opening in the end of the arm A, andenters an opening, h', in the end of the frame or support C, and thestem of this pin or screw h also forms the pivoton which the arm Boscillates, the stem passing through a suitable opening in the upper endof the arm, and when the gage E is used it is hung or suspended fromthis same pin or pivot 71, the stem of which passes through a suitableopening in the upper end of` the gage, by which construction it will beseen that the parts are all connected together by a single screw or pin,and this same screw crpin also forms the pivot on which the arms turn.

In operation7 the frame or support C is attached to the presser-bar ofthe machine by the head or socket C', and takes the place of the`ordinary presser-foot, and the arm A is connected by the slot A withthe needle-bar, when the device is ready for use. The ascent oftheneedle-bar raises the forward end of the arm A and causes the projectionc to engage with the end of the screw b, and the descent of theneedle-bar depresses the arm A and causes the projection a to engagewith the end of the screw b', producing aforward-and-back movement ofthe rufling-blade through the vibration of the arm B from the engagementof the projections c a with the ends of the screws b b when the gage isnot used, and when the gage is used the engagement of the projection ais made with the lip g, producing the same result. When the gage isused, the width of the plait or ruiile is determined by the point atwhich the gage-marks f on the plate E are set. l/Vhen the gage is notused, this width is determined by zuljusting the set-screw b to have itsend engaged by the projection to produce the required size of ruffle.

By using a separator made independent of the rufliing devices it will beseen that a piece of material of any width can be ruifled, as there is aclear space between the blade and the separator for the passage of thematerial.

The body of the separator is to be formed to adapt it to be attached tothe bed-plate of a sewing-machine and bring the acting portion G beneaththe rufiiing-blade and over the feed-dog, and will vary from that shownin order to suit different styles of machines, and, as shown, lips Z arestruck down from the body or main portion to enter the slot between thethroat-plate and bed-plate and form a lock to hold the separator iirmlyiu position.

Vhat I claim as new, and desire to secure by Letters Patent, is-

An arm, H, having its acting end provided with projections a a, incombination with an arm, B, carrying a rufiiing-blade and havingadjusting devices, gage E, and lframe or support C, substantially asdescribed. A
